The appender.setLayout(patternLayout); call generates a warning.
However, at that time the appender does not know its context.
Change
appender.setLayout(patternLayout);
appender.setContext(lc);
to
appender.setContext(lc);
appender.setLayout(patternLayout);
In which case you will get the warning message:
|-WARN - This appender no longer admits a layout as a sub-component, set
an encoder instead.
|-WARN - To ensure compatibility, wrapping your layout in
LayoutWrappingEncoder.
|-WARN - See also
http://logback.qos.ch/codes.html#layoutInsteadOfEncoder for details

further instructions.

Hi,
I’m using logback 0.9.28 and I’m trying to configure logback
programmatically with the following code:
public void prepare() {
LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();
lc.reset();
lc.getLogger("com").setLevel(Level.DEBUG);
lc.getLogger("com.example").setLevel(Level.DEBUG);
lc.getLogger("com.example.test").setLevel(Level.DEBUG);
lc.getLogger("com.example.test.inner").setLevel(Level.DEBUG);
PatternLayout patternLayout = new PatternLayout();
patternLayout.setContext(lc);
patternLayout.setPattern("%-5level %logger - %msg%n");
patternLayout.start();
ConsoleAppender<ILoggingEvent> appender = new
ConsoleAppender<ILoggingEvent>();
appender.setLayout(patternLayout);
appender.setContext(lc);
appender.start();
lc.getLogger("root").addAppender(appender);
lc.start();
StatusPrinter.printInCaseOfErrorsOrWarnings(lc);
super.prepare(testCase);
}
I keep getting the following message: LOGBACK: No context given for
ch.qos.logback.core.ConsoleAppender[null].
I’m seeing the log messages in the console, but I fail to understand why
I’m getting this message.
Thanks,
Shahar
